Abstract
Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as interfering species, ischemia, pH changes, temperatures changes, known or unknown sources of mechanical, electrical and/or biochemical noise, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system processes some or the entire data stream continually or intermittently based at least in part on whether the signal artifact event has occurred.
Claims20
A method of analyzing data from an analyte sensor, the method comprising:
- receiving data from the analyte sensor, the data comprising at least one sensor data point;
- determining whether a signal artifact event has occurred;
- and
- processing the received data, wherein the processing is based at least in part upon whether the signal artifact event has occurred.
A system configured to process data from an analyte sensor, the system comprising:
- a data receiving module configured to receive sensor data from the analyte sensor, the data comprising at least one sensor data point;
- a signal artifacts module configured to detect a signal artifact in the sensor data;
- and
- a processor module configured to process the sensor data, wherein processing is dependent at least in part upon whether the signal artifact is detected.
